I'm plannning to hack into my onstar GPS to drive my Delorme laptop navigatins software.

I need to know where the Vehicle Interface Unit (VIU) is located in my 2001 Silverado pickup. Does anyone know where it is located?

Under the upper dash pad, must be removed for access.

Easier to get the USB GPS antenna and plug it into the laptop. Rather than mess with winoncore software IMHO

yeah but the antenna isn't a flush fit external mount like the onstar one and may not give as good reception.

BTW anyone know the location in a 2003 Chevy 2500HD?
